Addiction is a deceptive by nature and addicts as well as their loved ones often fail to recognize it as the debilitating disease that it is because it lacks the more clearly defined perimeters of diseases such as cancer. It is often easy for everyone involved to dismiss addiction issues as moral failings or personal weaknesses, and addicts frequently lose their sense of self-worth as a result of this type of judgmental reaction. Interactions with friends, family, coworkers, and acquaintances involving anger and frustration over the addict's behavior further erode their self-esteem.
